1 Cor 9:20-23 NIV

To the Jews, I became like a Jew to win the Jews. To those under the law, I became like one under the law (though I myself am not under the law) so as to win those under the law. To those not having the law, I became like one not having the law (though I am not free from God’s law but am under Christ’s law) so as to win those not having the law. To the weak, I became weak to win the weak. I have become all things to all men so that by all possible means, I might save some. I do all this for the sake of the gospel so that I may share in its blessings. (1 Cor 9:20-23 NIV)
